and the corresponding hardness developed during quenching are predicted using Time Temperature Transformation (TTT) diagram incorporated in the analysis. To approve our work, dilation curves, Heisler charts......
, cohesion, elastic modulus, Poison’s ratio and dilation angle of soil) and the interface properties between piles and soils were analyzed in detail. The results show that the soil arch zone will become... a positive role in soil arching effects, but the Poisson’s ratio plays a negative role. The shear dilation angle has no conspicuous effect on the soil arching. Besides, the soil arch zone will enlarge......
in the discontinuities dip angle located in the roof will result in decrease in tensile stress of the roof. Stresses reaches to 8 MPa in the roof while due to dilation effect they reach up to 13......
, it has characteristics of large axial plastic deformation, obvious volumetric ductility dilation and large steady creep rate. The accelerated creep appears shortly after transient loading under......
into account, such as the initial phase of compaction and the latter stage of dilation. Thirdly, a method of determining model parameters was also presented. Finally, this model was used to compare... stage of dilation, are significant. Then, the macroscopic volumes of rocks are changed. However, the effect of volume change on rock deformation fails to be considered in the current models......
the ablation content of dilation part is the slightest for only thermochemistry ablation taking place. Key words: plasma spray forming; tungsten nozzle; hot isostatic pressing; ablation 固体火箭发动机的性能直接... magnification image; (d) White fine lamellar structure in high magnification image 图6 钨喉衬扩散段经烧蚀后的显微形貌 Fig.6 Ablation morphologies of dilation part of tungsten nozzle: (a) Panorama; (b......
rock and igneous rock is relatively large, whose average value is 0.140%. The rock will be softened with water which causes the grains expand internally and produced the dilation stress. The compression......
mass under hydraulic-mechanical coupling was proposed. It followed the generalized Mohr-Coulomb (M-C) failure criterion. This method considered the deterioration of the strength, deformation, dilation......
为 (1) 式中:；；；；；pi为灰度图像中灰度为i的像素出现的概率,；ni为灰度为i的像素在图像中的个数；n为图像总的像素个数. MATLAB编程实现孔隙判别与确定的流程如下:1) 批量读入经ImagePro软件处理后的CT扫描图片,将图像转换为灰度格式,并将原始图像进行备份；2) 采用中值滤波法滤除图像的噪声；3) 将灰度图片中的黑色背景区域滤除；4) 填充图片中的细小孔洞；5) 结合OTSU法确定各类材质的比对模板,通过原始灰度图片逐点像素比对确定像素的分类归属；6) 将最终的图像分割结果进行统计,以孔隙面积与试件截面积之比表示空隙率.当单个孔隙不与其他孔隙相连时表示为1个单独孔隙,对应......
. Dilated residual network (DRN) network proposed by YU et al replaces subsampling layers by adding dilation, which could be applied for semantic segmentation [25]. Our model utilizes dilated convolutions.... Both local and contextual information are important to understand the document structure. 3.1 Dilated convolutional network Dilation convolutional network is able to preserve spatial information [25......
